ISC class 12 minimum qualification mark
ISC 12th exams were conducted by CISCE Board from 13 February to 5 April 2025. The total time period for the principle part of the examination was 3 hours. English was a compulsory subject, and it will remain mandatory in the coming year.
To pass the exam, students have to get at least 40% marks in each subject of their respected section. To get a good score, students must know about the full course and the exam pattern.
It helps to understand what types of questions are asked, how marks are distributed to each subject, on which subjects to focus more, and what can be left smartly during modification.
In this article, I have also shared download links for the course PDF for each stream, which can be very useful during your preparation.

ISC Class 12 Exam Self Preparation Strategy
To prepare well for ISC class 12 exams, follow the steps given below:
- Start with the course:
First of all, read the latest course carefully and find out which topics are the most important or more points. - Wisely priority:
You must first start studying the subjects of those high-wages. - Go to less important chapters:
Then, you can go to the next part of the course that attains low points or less importance. - Practice last year’s question papers:
You should practice previous years ISC question papers to understand the exam pattern and marking scheme and how difficult the questions can be in the upcoming exam. - Note bullet-point:
In the first stage of your preparation, try making small notes in the form of bullet points. - Use your notes for amendment:
They will help when you modify the entire course just before the exam. - Regularly modify:
Try to modify regularly, and do not leave any subject listed in the 2025 course.
My last idea
I wrote this article after spending time in understanding the exam pattern, course update, and actually helps students in preparation for them. I tried to make everything easy and useful for all, whether you were from science, commerce or art.
First, the course may look large and misleading. But if you go to the subject from the subject, it becomes very easy to handle.
Always remember that you do not have to study hard; Study smart. Give more time to important chapters, revise repeatedly, and not forget to make your small notes. These small habits help a lot in the end.
If this article helped you, then your preparation is already going in the right direction.
Best wishes, give your best effort!
